Main display toggling off and on

Hi all,
Running the live USB at the moment for trialling. Whenever I login, my main screen will go black before returning after a second or two. It happens every 30s or so but my second monitor is fine.
Any thoughts would be appreciated.

AMD Ryzen 5 7600X and RX 6750XT, bazzite-stable.iso

Screens both work fine in windows. There is a KVM in between both monitors and desktop.
Solution
Nvm it was refresh rate. Set to 144hz which it should be capable of.
